JOHN E. JOHNSOIJ, O13 FOREST CITY, IOJVA.

To all "whom, it may concern:

Be it known that I, Join: R. JOHXSON, a subject to the King of Sweden, and resident of Forest City, Iowa, have invented certain new and useful. Improvements in Driving Mechanism for Motor-Vehicles, of which the following is a specification.

This invention relates to improvements in a driving mechanism for motor vehicles, and has for its object a worm drive mechanism which is pretenhly located on the front of a motor vehicle and is so arranged as to enable the wheels to be driven and steered at the same time.

A further object of my invention is to provide the front wheels ot the motor vehicle with a driving mechanism and at the same time allow them to he steered in any direction.

Figure 1, is a horizontal sectional \lGW of one of the front wheels of the motor vehicle embodying my invent-ion.

.Fig'. 2, is a vertical sectional view of the same.

Fig. 3, is a vertical crosssectional View.

Referring to the drawings in detail & indicates a wheel of an ordinary motor truck or the like, the same being provided with a hub 5, by which the wheel: is sup' The axle 6 is supported in the housing 7,-which is preferably constructed of two parts so that the several parts can he readil assembled,

In this housing is located a worm gear .8; this gear is keyed to the hub 5, and by means of this gear the wheel is placcdin rotation on the axle 6.

The axle (3 is held stationary lug by means of the pin 9. In the housing is supported a vertical worm 10. which is mounted on the shaft 11. and the shaft. has

bearing in both parts of the housing.

In the upper and lower portion ot the housing concentric with the shaft 11 are formed trunnions l2 and 13 which have hearing in the bifurcated arn 1-1 of the axle 15, and are introduced'by it-moving the caps 14- bolted to the ends.

Opposite. the trunnions 1'2 and 13- vtorn'ied any car 24 in which mounted a rod 23. This rod 23 being a portion of the ordinary steering gear of a motor vehicles The bifurcation on the ends of the axle 15 are of such depth as to allow therear end 16 ot the housing perfect freedom during the steering movement of the Wheels.

On top of the axle 15 provii'" tension 17 which acts as a hearing shaft 1 the ends or' which are provir. M with a beveled gear 19 which lnizslies beveled 2O u'iouuted on the top oi the shaft 11.
